Philippines-born, Netherlands-bred maestro Laidback Luke is the ultrapopular big-room pop-houser who has reworked tracks from the likes of the Black Eyed Peas and Christina Aguilera into clubland hits over the past few years; tonight he headlines at Terminal 5. There's plenty of other talent on hand as well, including Martin Solveig—the Parisian DJ and producer who tends to incorporate heavy doses of funk and rock into his sets—and dark-electropop artist Mt. Sims.
